We have two migrations running through the OpsHub Visual Studio Online Migration Utility that have slowed down to what has seemed a halt. Is there any way to tell if it is still running? No changesets have moved within the past 3 hours. (only 25 moved on one project in one day). If I were to stop the migration and restart it, will it continue from where it stopped or will it restart again and the past week and a half of migration is lost?
If you were to STOP a running migration and re-start the same one after a while, it will continue from the point where it stopped. You will not lose any data in such situation.
What is the average no. of files involved in your normal change-set? Larger change-sets do take some time to migrate. You can refer the OpsHubTFSService.log file in the installation-location/logs/ folder to intricately follow what the tool is currently doing in terms of processing data.
